Title: Air quantity controller
Inventor: EGAMI TOYOHIKO
IPC: F23N5/18
Filed: 1990-03-30
Abstract: PURPOSE:To obtain an air quantity controller which can feed and control a proper air quantity even when the characteristic of a sensor changes by providing a fan driving means for adding a corrected value during pre-purging to the output of the air quantity sensor detected in accordance with the operating state of the fan and calculating and outputting the driving output of the fan. CONSTITUTION:The characteristic of an air quantity sensor 3 changes due to aged deterioration or the adhesion of dust for a long time. When an air quantity is controlled with characteristic g(w) at this time maintained, even if the driving voltage of a fan is outputted at w2 and the air quantity is actually proper, the air quantity sensor 3 cutputs V4. Namely, only the air quantity corresponding to the output of w3 is detected, the output of the fan is increased until the sensor outputs V2 to thereby obtain w4. Then, air/fuel ratio changes to cause an abnormal combustion. Thus, a correcting means 63 compares an initial characteristic f(w) with the present characteristic g(w) and calculates the difference therebetween to obtain the corrected value. Then, the corrected value is added to the present characteristic g(w) to obtain a corrected characteristic h(w), so that the driving output of the fan is controlled based thereon. The initial value and the present value of the output of the air quantity sensor are detected during pre-purging.

Title: Motor-operated valve positioning control method
Inventor: NAKADA HIROYUKI
IPC: F16K31/04
Filed: 1990-03-30
Abstract: PURPOSE:To determine the position of a valve smoothly according to the load fluctuation of the valve by enlarging deceleration starting position deviation in the case of an motor-operated valve not being decelerated down to the command positioning speed, and reducing positioning speed in the case of the valve being out of the dead zone when the stop of a motor. CONSTITUTION:A target position signal 1 is read first, and then a present position detection signal 8 is read from a position detecting part 7. This present position detection signal 8 is fed back to a control part 2 so as to compute deviation between a target position and the present position and to judge this deviation value. The control part 2 determines whether a motor M is to be operated at normal speed, decelerated or stopped respectively depending on deviation > positioning starting deviation, positioning starting deviation >= deviation > dead zone, or deviation <= dead zone. In this case, a judgement is made from the data during deceleration given from the position detecting part 7, and when the deceleration is incomplete, the deceleration starting position deviation is enlarged. In the case of no change in the target position no valve entering the dead zone after the stop of the motor M, mode shift is performed to reduce the positioning speed. This action is repeated every time when the target position is changed.

IPC: G01B11/02
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To measure the length of a traveling vehicle with a simple structure in no contact by calculating it with the light reception signal data of photoelectric sensors provided at two positions separated at the prescribed distance. SOLUTION: Photoelectric sensors 1a, 1b are installed at two positions along a road separated at the prescribed distance in the vehicle traveling direction. The light reception signals of the photoelectric sensors 1a, 1b are binary-changed when light is received or shielded, and the light reception signals are transmitted to the input process section 7 of a measurement arithmetic device 6 by wires or radio on the real-time basis. The input process section 7 removes the unnecessary noises of the ever-changing light reception signals from the photoelectric sensors 1a, 1b and transfers the signals to an A/D converter 8. The A/D- converted digital data of the light reception signals of the photoelectric sensors 1a, 1b are sent to an arithmetic process section 9.  The arithmetic process section 9 determines the length of a traveling vehicle passing through the position of the photoelectric sensors 1a, 1b based on the input data, classifies the traveling vehicle into a large vehicle or a small vehicle from the length, and forms the information on the number of vehicles and average speed for each classification in 1min, for example, as the measured information of a traffic volume.

Title: Steel ball detecting sensor
Inventor: KOBAYASHI TAKANOBU
IPC: G06M7/00
Filed: 1994-04-25
Abstract: PURPOSE:To provide the steel ball detecting sensor with which a steel ball can be prevented from being erroneously detected and a space around a passing hole inside the main body of the sensor is not decreased. CONSTITUTION:This sensor is provided with a main body 1 of the sensor equipped with a through hole 2, which cross-section is almost circularly formed, and a detecting coil 3 wound around the hole 2 inside the main body 1 of the sensor. Peripheral edge part 2a at both the opening edges of the hole 2 are circumscribed to the almost circular peripheral edge of the hole 2, rectangularly formed to the form which area are added to corner parts, and tapered to be inclined toward the inside of the main body 1 of the sensor. Therefore, even when the steel ball touches the opening end peripheral edge parts 2a of the hole 2, it non-uniformly moves along the rectangular peripheral edge parts 2a. Accordingly, velocity for the steel ball to pass through the hole 2 is accelerated in comparison with the case that the opening end peripheral edge parts 2a are almost circular, and the erroneous detection can be prevented. Further, the cross-sectional shape of the hole 2 excepting for the opening end peripheral edge parts 2a is almost circular, and a space 4 around the hole 2 is not decreased.
